IMPROVEMENT m PAlNT-BRUS HES.

Specification forming part of LettersPatent No. 138,787, dated May 13, 1873; application filed October 19, 1872.

To all whom it may concern:

Be it known that I, GEORGE E. OHINNooK, of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Painters Brushes, of which the following is a specification:

This invention consists in a novel means of tightening in place the bristles of painters brushes whereby the same may be securely fixed in position with any required degree of tightness or compression previous to the attachment of the handle, so that all liability of imperfect retention of the bristles, or of their detachment in the subsequent use of the brush, is avoided.

Figure 1 is a longitudinal section of a brush constructed according to my invention. Fig. 2 is a plan view of a brush-head with the handle and its block detached therefrom.

The brush-head A comprises the annular top or holding-band a, whichmay be of wire wound in coils in continuous contact with each other, and soldered or brazed together; the bristles b, which are compressed at one end to any convenient degree, and the said end thrust into the band a one-half or thereabout of the distance through the same; and the pegs 0, which are driven into the top or inner end of the mass of bristles, as shown more clearly in Fig. 1, while the dispersed arrangement of the said pegs is more plainly represented in Fig. 2.

Previous to the insertion of the pegs, which may be done in any convenient manner, the inner or inclosed end of the mass of bristles is saturated with melted resin, which agglutinates the end portions of the bristles, and,

afterward hardening, cements them to each other and also to the rougher surfaces of the wood of which the pegs are made, and thereby assists the pegs in holding the bristles in place.

If desired, the pegs, after being driven to their places, may be themselves expanded by driving metallic nails longitudinally into them, as shown at a in Fig. 1.

It will be especially kept in mind that the result aforesaid is due to the use of a number of pegs distributed at different parts of the inner end of the mass of bristles, and thereby distributing the compressing action throughout the same, and also affording additional holding surface for the cement, as just herein set forth; whereas, the employment of a single key, driven longitudinally into the bristles, would simply confine the same in contact with each other in an annular mass between such key and the band w-an arrangement found in practice incapable of permanently retaining the bristles in place.

When the brush-head, constructed as de scribed, has been completed the handle B, provided at its inner end with the block at, corresponding in size and shape to the unoccupied or outermost portion of the top or holding-band a, has such block pressed snugly into such portion of the ban d, and cemented fast therein with resin or equivalent cement.

By thus forming the brush-head separately,

and afterward attaching the handle andits block, the construction of both the aforesaid portions is very materially facilitated, and the cost of manufacturing the brush complete correspondingly diminished.

What I claim as my invention is- The combination of the system of isolated pegs, made and applied separate and distinct from the handle-butt, with the bristles and top or holding-band, whereby provision is made for the efficient tightening of the bristles to any requisite degree previous to the attachment of the handle, substantially as herein set forth.
